A radio telescope on the scale of Arecibo - where you are after extremely large surface area for detection of faint signals - is limited by the size of the dish. Arecibo was 73,000 square meters while JWST is "only" 25 square meters. For this, building it in a crater on the moon and allowing the moon itself to help support it is advantageous. ... and has some interesting scaling up possible. https://www.researchgate.net/publication/258694444_Implementing_planetary_meteor_impact_craters_as_high_gain_radio_frequency_dish_reflector_antennas https://www.researchgate.net/publication/258694444_Implement...
